OpenGL SFML GLEW Setup Not Working Access Violation Exception

I am currently attempting to get started with OpenGL using SFML and GLEW. The problem I am having is with GLEW.

The code is as follows:

#include <GL/glew.h>
#include <SFML/Window.hpp>
#include <SFML/OpenGL.hpp>

int main()
{

	//Initialize Glew
	glewExperimental = GL_TRUE;
	glewInit();

	GLuint vertexBuffer;
	glGenBuffers(1, &vertexBuffer); //*
	printf("%u
", vertexBuffer);

    // create the window
    sf::Window window(sf::VideoMode::getDesktopMode(), "IsoWars", sf::Style::Fullscreen, sf::ContextSettings(32));
    window.setVerticalSyncEnabled(true);

    // load resources, initialize the OpenGL states, ...

    // run the main loop
    bool running = true;
    while (running)
    {
        // clear the buffers
        glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

        // draw...

        // end the current frame (internally swaps the front and back buffers)
        window.display();

        // handle events
        sf::Event event;
        while (window.pollEvent(event))
        {
			switch (event.type)
			{
			case sf::Event::Closed:
                // end the program
                running = false;
				break;
			case sf::Event::KeyPressed:
				switch (event.key.code)
				{
				case sf::Keyboard::Escape:
					running = false;
					break;
				}
            }
        }
    }

    // release resources...

    return 0;
}

The call to ‘glGenBuffers(1, &vertexBuffer);’ gives an access violation similar to this (which the forum wont let me post):

If I comment that out, the program runs fine. I need to get GLEW working/configured properly.

I’m using Microsoft Visual C++ 2010. Here is my configuration (again sorry - the forum wont let me post images properly):

My system is 64 bit. I’ve tried both glew32.dlls that come with it, and both glew32s.dlls (with the GLEW_STATIC #defined). Does anyone know what I’ve done wrong in the setup?

First, open your window to get a valid opengl context.
Then,initialize glew and then you should be able to start making opengl calls.
